Reads live weight over RS-232 · no double entry · no retyping from the indicator

How a weighment runs

from ramp to receipt.

Every step happens on one screen. The operator never retypes a number the scale already knows.

  1. 1Vehicle rolls on

    Weight appears as it happens

    An agent on the weighbridge PC reads the indicator and streams the weight live. It shows on the operator's screen, in the office and anywhere you're signed in.

    42380 kg · live
  2. 2Accept when stable

    First weighment, locked in

    Pick the party, vehicle and material from search as you type. Accept saves the reading straight from the scale, and nobody can type in a number by hand.

    Gross · 11:42
  3. 3Vehicle returns

    Second weighment pairs up

    The return trip links to the first ticket automatically. Tare is subtracted and net weight is worked out for you, loaded or empty first.

    Net 28,260 kg
  4. 4Settle and print

    Paid, or on account

    Take cash, UPI, card or bank transfer, or post the bill to the customer's credit account. The slip prints in the format that customer prefers.

What's inside

the whole weighbridge office.

Weighing, billing, credit, tax and reporting are built as one system. You don't need three tools that disagree with each other.

Live weight you can trust

If the scale goes quiet, the number disappears.

A reading older than two seconds is never shown as live. If the cable drops or the indicator freezes, the display blanks and Accept is disabled, so no one bills a stale weight. The saved weight always comes from the scale, never from the screen.

Every party gets the bill, instantly

As soon as a bill is saved, the buyer, seller and trader on the ticket each get a copy by WhatsApp, SMS and email. Each customer chooses how they want to receive it.

Weigh slips

The slip your customers already know

Pick a default for the business, override it per weighbridge, and remember each customer's preference. Your existing pre-printed stationery still works.

GST tax invoices

Numbered right, frozen once issued

Turn GST on when you need it. GSTINs are checked as you type, CGST/SGST or IGST is split by state, and every invoice takes the next number in its financial-year series.

Customer credit

A ledger that can't be quietly edited

Credit bills, payments and receipts go into an append-only ledger. A mistake is reversed with a new entry, never deleted. Ageing shows who is overdue and by how much.

Everyone sees what their job needs

Operators weigh and take payments. Managers adjust limits and void entries. Admins set up the business. Every change goes into an audit log.

Centralised management

one office for every weighbridge.

Set everything up once, from anywhere. Every site uses the same settings, and changes don't need anyone to drive out and fix the PC.

Configure sites remotely

Indicator serial settings, slip formats and GST details are set from the office. The weighbridge PC picks them up by itself.

Business defaults, site overrides

Choose a slip format for the whole business. A weighbridge changes only what's different about it.

Know when a site goes down

Every site reports in live, so you see a scale or PC go offline before a driver has to call you.

One team, one set of records

Staff, roles, customers, vehicles, materials and transporters are shared across every weighbridge, and each change is written to the audit log.

Where it started
Infraweigh runs daily weighments at Anand Steels & Cements. Every feature here was needed at a real window, with real trucks waiting.
Your hardware
Keep your indicator and printer. A small agent on the weighbridge PC reads the serial port. You set the baud rate and format in the app.
Your data
Each business's records are kept separate, and every weighbridge has its own address for your team.
Getting started
We set up your weighbridges, customers and slip format with you. Your operators can start weighing the same day.
